AI Thread Summary
To calculate the torque required for a sphere to exit a countersink, the key factors include the force applied by the spring, the dimensions of the sphere, and the geometry of the countersink. The spring exerts a force of 76.26N at a compression of 11.6mm, while the sphere has a fixed diameter of 6.0mm and the countersink measures 0.5mm with a 45° angle. Understanding the interaction between these components is crucial for determining the torque in Newton-meters (Nm) needed to prevent motor issues in a coffee milling appliance. Additional clarification or visual aids may be necessary for precise calculations. The discussion emphasizes the importance of these variables in ensuring effective operation.

I need help (in a very simple way) due to calculate the torque needed to let a sphere coming out of a countersink.
I'll try to explain better my application with the components involved:
1. a spring that apply a Force F=76.26N (nominal length 14mm) at 11.6mm of compression: these values could be variable;
2. a ball bearing sphere 6.0mm diameter: this is a fixed value;
3. a countersink of 0.5mm x 45° in a 5.0mm hole (the height and the angle could be variable);
The spring push the sphere inside the countersink hole.
The countersink holes are cnc in a coffee milling appliance and I need to know the torque in Nm to let the sphere coming out of the countersink (this is used to avoid problems on the driving motor).
If needed I can try explain better with a drawing.

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
Thread 'What's the most likely cause for this carbon seal crack?'
We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
